Explanation / Answer
1. F = kq1q2/r^2
F is inversely proportional to r, So when r is very short electrical force will be high
Option B. Close together
2. F = kq1q2/r^2
So you can see that electrical force depend on the magnitude of charge also seperation between them.
Option C. magnitude and separation distance.
3. electron and proton have negative and positive charges respectively. And you should remember that opposite charges attracts each other.
option C attract each other
4. Polarisedmeans positive on one end, negative on the other end but no overall charge.
option C its charges have been rearranged.
5. E = F/q
option D a proton.
